Marline 4Ch DVR 5MP

A 4-Channel DVR (Digital Video Recorder) that supports 5 MP cameras is a security recording device used in CCTV systems. “4 Channel” means it can connect up to four cameras for recording and monitoring at the same time. “5 MP” means it supports cameras with up to 5-megapixel resolution, which provides high-definition video detail.

• Supports 4 video channels — connect four cameras simultaneously.
• Compatible with multiple analog camera formats (TVI, AHD, CVI, CVBS) and sometimes IP cameras; this is often called 5-in-1 (or multi-format) support.

Accepts 5 MP video input from cameras (usually at a frame rate like ~12 fps per channel).
• Records video from each camera and stores it to an internal hard drive (HDD). You need to install a SATA HDD (often up to ~6–8 TB, depending on the DVR).

• Connect to a monitor via HDMI or VGA to view live or recorded video.
• You can also view footage remotely via a smartphone or PC app over the network (depending on model support).
